The GoalZero Yeti 1400 Lithium V2 Solar Kit is the solution to expansive power needs when you want to avoid generator use. The Yeti 1400 operates as a quiet, clean-running alternative that can power your devices for events, power outages, or camping. It uses a lithium-ion battery that is protected by a water-tight enclosure to keep things safe inside or outside, and it can be replaced by the user for a longer lifespan of the entire system. Wi-Fi connectivity allows you to control the Yeti from your mobile device, so you aren't constantly making your way over when there's fun to be had. The Boulder 100 Briefcase is built with tempered glass that can stand up to rigorous use, and delivers a powerful 100 watts to the system when used in optimal conditions.
